8. The Water Online Show: What NASA Satellites Reveal About Earth's Shrinking Freshwater 9/10/2025

   In this episode of In The Flow, hosts Travis Kennedy and Kevin Westerling delve into one of the most pressing issues facing water managers throughout the world: the shrinking supply of freshwater.

9. The Role Of Turbine Flow Meters In Wastewater Treatment Plants 9/10/2025

   Wastewater plants are made up of a series of interconnected processes, each one dependent on accurate data. Turbine flow meters can be installed at several stages to provide operators with real-time, trustworthy flow information.

10. Constant vs. Proportional Diffusivity In RSSCT: Choosing The Right Model For GAC Performance Testing 9/9/2025

    When designing adsorption systems for PFAS removal, utilities and engineers increasingly rely on RSSCTs (Rapid Small-Scale Column Tests) to compare the performance of granular activated carbon (GAC) or other sorbents. One often overlooked yet critical assumption in RSSCT modeling is the choice between constant diffusivity and proportional diffusivity. Though both approaches are valid, selecting the right model can significantly impact how well bench-scale results translate to full-scale systems.
